- چکیده:
- چکیده انگلیسی: A convenient synthetic route for the synthesis of biologically active functionalized piperidines using
Zn(OAc)2.2H2O as a highly efficient catalyst via five-component reaction of aromatic aldehydes,
anilines and β-ketoesters at ambient temperature has studied. Mild reaction conditions, simplicity of
operation and work-up procedures with no necessity of chromatographic purification steps, the
availability and easy to handle of this solid catalyst and good to high yields are the notable benefits
for the highly efficient synthesis of these products.

- کلمات کلیدی: Solvent-free conditions,Sodium bismuthate (NaBiO3),Spiro[4H-pyran]derivatives,Biologically active compounds,One-pot operation
- چکیده:
- چکیده انگلیسی: An efficient sodium bismuthate (NaBiO3) synthesis of biologically active spiro[4H-pyran]
derivatives has been accomplished via one-pot three-condensation of isatin/acenaphthequinone, malononitrile and different reagents including 1,3-dicrbonyl compounds, α-naphthol and 4-hydroxycumarin under solvent-free conditions. The notable advantages of the present procedure are: eco-friendly, environmentally benign nature,low-cost and non-toxic catalyst, simplicity of operation with no necessity of chromatographic
purification steps, short reaction times, good to high yields and solvent-free conditions.

- چکیده:
- چکیده انگلیسی: In this research study, a green synthetic route for eco-safe and solvent-free preparation of 12-aryl-tetrahydrobenzo[α]xanthene-11-ones, 1,8-dioxo-octahydroxanthenes and 14-aryl-14H-dibenzo[α,j]xanthenes using formic acid as a bio-based, natural and versatile catalyst was developed. The notable advantages of this green approach are use of bio-based, natural, easy-to-handle and available readily green catalyst, absence of hazardous organic solvents, solvent-free conditions with good to high yields and short reaction times and one-pot reactions. Furthermore, one of the source of environmental pollutions is the usage of organic solvents under reflux conditions and the need for column chromatography to purity the products. In this present work, the products were obtained through simple filter with no need column chromatographic separation.
